PLOWSHAR-E.

Application filed June 8,

NICOL, a subject of the King of Great Brit ain, and residing atHuntingdon, in the Province of Quebec, in the Dominion of Canada, haveinvented al new and useful Improvement in a Plowshare, of'which thefollowing is the specification.

The invention relates to a plowshare as described in the presentspecication and shown in the accompanying drawings that form part of thesame.

The invention consists essentially of the novel features pointed outbroadly and specifically in the claims for novelty following adescription containing an explanation in detail of an acceptable form ofthe invention.

The objects of the invention are to reduce the expense incident to therenewal of the penetrating point of the plow and to effect an adjustmentof the implement according to the stature of the operator withoutresorting to replacements or shop work; to fa. cilitate the operation ofplowing with Walle ing, gang or tractor plows; to reinforce theimplement where most needed and thereby reduce the breakages; and toprovide a du rable plowshare formed to carry a replaceable digger.

In the drawings, Figure 1 is a perspective view of a gang plow, showingthe plowshare constructed according to this invention.

Figure 2 is a perspective view of a walking plow showing this inventionin its construction.

Figure 3 is a perspective detail of the landside plate showing the outerside.

Figure 4 is a perspective detail of the landside plate, showing theinner side.

Figure 5 is an inside elevation of the landside plate.

Figure 6 is a perspective detail of the landside running plate.

Figure 7 is a vertical and cross sectional view of the landside platesassembled and digging bar in its adjusting slide.

Figure 8 is a sectional and plan view showing the feather base,adjusting slide full, and landside plate in sect-ion.

Figure 9 is a perspective detail of the digging bar.

Like numerals of reference indicate corresponding parts in the variousfigures.

Referring to the drawings, the landside 1923. Serial No. 644,149.

platel is formed with a reduced upper end 2 and. a yreducedlower end 3and tapers in thickness in the direction of the front end, where it isreinforced by a rib 4 extending into the feather base 5, through whichthe rectangular bar hole 6 extends. The adjusting and parallel slidebrackets 7 and 8 are secured through the lugs 9 and 10 to the innersurface of the landside plate 1 and extend in an upwardly inclineddirection in alignment with the upper and lower wall surfaces of the barhole 6 respectively.

The brackets 7 and 8 stand out from the plate surface, leaving aconsiderable clearance, being held to that position by said lugs 9 and10, and these brackets are pierced at intervals with the bolt holes 11respectively.

rlhe digging bar 12 is sharpened at the front end to form a spade edge13 and to- Vwards the other end has the bolt holes 14 and 15 through oneof which and two bolt holes 11 it is held between the brackets 7 and 8,this bar extending through the bar hole 6 and out beyond the featherbase 5 to the extent found desirable by the operator.

The feather 16 is shaped much the same as any plow share feather, buthas the slot 17 cut away from the inner point side to permit the diggingbar 12 to pass through to its operating position.

The feather 16 is secured to the feather base 5 by the screws 18 and thelandside running plate 19 is secured by the bolts 2O and fills in thelower reduced end 8 of the landside plate 1, and in thickness in bothbottom and side plates tapers from the rear to the front.

rThe mould board or plate 21 is secured to the front of the landsideplate 1 over the rib 4 and to the feather 5 by the screws 22 and meetsthe reduced inner end 23 of the feather.

ln installing this plowshare in gang or tractor plows they are rigidlyheld by the curved arms 24 and the implement operated as usual though atany time the adjustable point may be moved forwardly until worn out andthen exchanged.

lny a walking plow the draft beam 25 is secured to the upper reduced end2 and the handles 26 to the beam and mould plate as customary.

been removable;r points I do :not'knowfy any plow similarly'constructedorl arranged.

What I claim isz- A plowshare comprisnga landsideplete 5 having areduced upper end and a reduced lower end and a pierced boss at thelowerl front end forming a feather base; said plate tapering inlongitudinal section from rear to front7 a slotted feather secured tosaid 1U baSe,` a'f'rnould; board, ai runnngf plate tap'red inthickness"fr0ni-frear fto fronty and removably secu-red to ssaidV'reduced lower e1id,-p'arallel@ brackets l"secured to 'the :innersurface of said landside plate and inclined longitudinally and forming abar slide in longitudinal alignment With said pierced lug and a diggingbar adjustably secured in said slide and pierced lug.
